Technical Field

[0001] The invention relates to the technical field of positioning, and in particular to a device and method for installing and positioning a curved surface building steel structure. Background Art

[0002] Curved buildings refer to buildings that use non-traditional geometric shapes in the design and construction process, especially those with irregular, nonlinear or dynamic forms. Such buildings are often realized through complex calculations and advanced manufacturing technologies, and their structural forms and appearance are usually expressive and innovative. Curved buildings, with their unique aesthetics and structural characteristics, are becoming an important direction in modern architectural design.

[0003] The irregularly curved building mainly uses steel structure as the skeleton. Therefore, during the installation process, the position of the steel columns needs to be accurately located first. Moreover, the steel columns are not evenly spaced. Therefore, each steel column is prone to deviation during the erection and installation. As the number of steel columns increases, the error will also increase, eventually resulting in some steel columns needing to be reinstalled and calibrated.

[0013] Preferably, a control panel is installed inside the box, and the control panel is connected to the XY module, the turntable, the electric push rod and the laser rangefinder through wires to control the laser rangefinder to locate each installation point.

[0014] A method for installing and positioning a steel structure of a building with a special curved surface, the specific operations are as follows:

[0015] S1. According to the requirements of the building drawings, determine the position of each steel column installation point and set the origin. Display each steel column installation point through coordinates, place the box on the origin of the building ground, and unfold the folding column. Then, adjust the box level through the support structure according to the level meter, and restore the XY module, turntable and electric push rod to their initial state. The bottom point of the box corresponding to the folding column is used as the origin, and the laser rangefinder points to the X axis;

[0016] S2. Determine the coordinates A(x,y) of the first steel column installation point. According to the formula a+b=c, substitute x and y into a and b in the formula to calculate the c value, which is the distance S from the origin of the box to point A. If S=x, the coordinates A(x,y) are on the X-axis and the turntable does not need to run. If S=y, the coordinates A(x,y) are on the Y-axis. The turntable drives the laser rangefinder on it to rotate 90° so that the laser rangefinder points to the Y-axis. If S is greater than x and y, the horizontal rotation angle α of the laser rangefinder is calculated according to the right-angle trigonometric function formula sinα=y / S, and the turntable is controlled to drive the laser rangefinder on it to rotate to the specified angle.

[0017] S3. The height H of the level is known. Then, according to the formula a+b=c, the distance L from the laser rangefinder to the coordinate A is calculated. Then, according to the formula sinθ=S / L, the angle θ of the laser rangefinder's up and down rotation is calculated. In this way, the turntable and the electric push rod are controlled to drive the laser rangefinder to adjust to the specified angle, and the point mapped by the laser rangefinder on the ground is A(x,y);

[0018] S4. Then, according to the size of the steel column base on the drawing, adjust the XY module so that the XY module drives the level to move horizontally on the XY axis, and map points B, C and D on the ground. Determine the location and size of the installation point through points A, B, C and D. Use points A, B, C and D to determine the four corners of the steel column base. After determining the installation point, mark it on the ground. Finally, the XY module drives the folding column back to its original position, and the turntable and electric push rod drive the laser rangefinder to restore to its initial state. Position each installation point of the steel column according to the above operations.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The equipment uses a laser rangefinder and an electronic push rod to accurately measure distance and refine positioning accuracy, so that it can point to a specific positioning point, thereby providing more accurate measurement data.

[0040] See also Figure 4 The XY module 3 includes an X-axis linear module 31 installed inside the box 1 and a Y-axis linear module 32 installed on the slide of the X-axis linear module 31, and sliders 33 are installed at both ends of the Y-axis linear module 32, and slide rails 34 are installed on both sides of the box 1, and the two ends of the Y-axis linear module 32 slide on the slide rails 34 through the sliders 33, and the two ends of the Y-axis linear module 32 are supported by the slide rails 34 during the movement, so that the Y-axis linear module 32 remains stable.

[0041] See also Figure 5 and Figure 6The turntable 5 includes a shell 51 installed on the platform 4, and a rotatable gear 52 is provided inside the shell 51, a slidable rack 53 is provided inside the shell 51, and an electric cylinder 54 is installed on the outside of the shell 51, and the moving end of the electric cylinder 54 is connected to the rack 53, and pushes the rack 53 to engage with the gear 52. The top of the shell 51 is connected to the end cover 55 through a turntable bearing, and the axial end of the gear 52 is connected to the center of the end cover 55. The gear 52 is driven to rotate by the rack 53, so that the end cover 55 drives the folding column 6 thereon to adjust the orientation. A base 56 is installed inside the shell 51, and the top of the base 56 is slidably connected to the bottom end of the rack 53.

[0042] An angle sensor is provided at the shaft end of the gear 52, and the electric cylinder 54 pushes the rack 53 to slide on the base 56 and drives the gear 52 to rotate. The rotation angle of the gear 52 can be controlled by controlling the telescopic length of the electric cylinder 54, and the rack 53 can drive the gear 52 to rotate one circle, so that the end cover 55 drives the components thereon to rotate within a range of 360 degrees. Compared with the motor drive, the electric cylinder 54 pushes the rack 53 to drive the gear 52 to rotate, and it is easier to control the rotation angle.

[0043] See also Figure 7 The folding column 6 includes a U-shaped base 61 installed on the turntable 5, and an A support column 62 is hinged on the U-shaped base 61, the top of the A support column 62 is hinged to a connecting piece 63, the connecting piece 63 is hinged to a B support column 64, and the laser rangefinder 7 is hinged to the B support column 64, and the U-shaped base 61 and the connecting piece 63 are both provided with pins for positioning the A support column 62 and the B support column 64.

[0044] The folding column 6 needs to be manually unfolded and folded. During the unfolding process, the U-shaped base 61, the A support column 62, the connecting piece 63 and the B support column 64 need to be kept on a horizontal line, and the A support column 62 and the B support column 64 are fixed by a latch to prevent the A support column 62 and the B support column 64 from moving. The A support column 62 and the B support column 64 are provided with holes for inserting the latch, so that the U-shaped base 61, the A support column 62, the connecting piece 63 and the B support column 64 will not be deformed after being unfolded, and when the folding column 6 is folded, Figure 7 The folding rotation direction of the U-shaped base 61 and the A support column 62 is different from the folding rotation direction of the A support column 62 and the B support column 64 and the connecting member 63, so that the folding column 6 shrinks in the box body 1 after being folded.

[0045] A plurality of rollers 10 are disposed on one side of the box body 1, and a hidden retractable handle 11 is disposed on a side of the box body 1 away from the rollers 10, so that the box body 1 can be moved like a suitcase for easy transfer.

[0046] The four corners of the bottom end of the box body 1 are provided with supporting structures 9, and a spirit level 12 for detecting the horizontal and vertical state of the box body 1 is embedded on the box body 1. The level of the box body 1 is adjusted by the supporting structure 9, and the horizontal and vertical state of the box body 1 can be detected by the spirit level 12. The folding column 6 must maintain a vertical state after unfolding, so it is necessary to adjust the horizontal and vertical state of the box body 1 to prevent errors in the installation point.

[0047] See also Figure 8 The support structure 9 includes a fixed plate 91 installed inside the box body 1, and a spline 92 is installed at the bottom end of the fixed plate 91. A slidable threaded column 93 is provided at the bottom end of the spline 92, and the threaded column 93 extends from the bottom end of the box body 1 and is connected to the support plate 94. An adjusting wheel 95 is threadedly connected to the threaded column 93, and the adjusting wheel 95 is guided out from the notch on the side of the box body 1. The threaded column 93 is controlled to be extended and retracted by rotating the adjusting wheel 95, and the supporting distance of the support plate 94 to the box body 1 is adjusted to make the box body 1 adjusted to a horizontal state. The adjusting wheel 95 is rotated. Since the adjusting wheel 95 can only rotate but cannot move up and down, and under the positioning of the spline 92, the threaded column 93 drives the support plate 94 to be extended and retracted. The level of the box body 1 can be adjusted by using four support structures 9 to avoid the box body 1 from tilting, which causes a deviation in the position of the detected installation point.

[0048] A control panel is installed inside the box 1, and the control panel is connected to the XY module 3, the turntable 5, the electric push rod 8 and the laser rangefinder 7 through wires, so as to control the laser rangefinder 7 to locate each installation point. The coordinates of the steel column and the base size are input on the control panel, so that the control panel drives the turntable 5 to rotate, and the laser rangefinder 7 is adjusted in the horizontal direction. Then, the vertical angle of the laser rangefinder 7 is adjusted by the electric push rod 8, and finally, the laser rangefinder 7 is turned on. The laser rangefinder 7 forms a distance measuring light spot on the ground, so that the workers can draw marks on the ground to determine the position of the installation point.

[0049] A method for installing and positioning a steel structure of a building with a different curved surface, the specific operations are as follows:

[0050] S1. According to the requirements of the building drawings, determine the position of each steel column installation point, set the origin, display each steel column installation point through coordinates, place the box 1 on the origin of the building ground, and unfold the folding column 6. Then, according to the level 12, adjust the level of the box 1 through the support structure 9, and restore the XY module 3, the turntable 5 and the electric push rod 8 to their initial states. The bottom point of the box 1 corresponding to the folding column 6 is used as the origin, and the laser rangefinder 7 points to the X axis;

[0051] S2. Determine the coordinates A(x,y) of the first steel column installation point, according to formula a 2 +b 2 =c 2, substitute x and y into a and b in the formula, and calculate the value of c, which is the distance S from the origin of box 1 to point A. If S = x, then the coordinate A (x, y) is on the X-axis (such as Fig. 9 ), the turntable 5 does not need to run, if S = y, then the coordinate A (x, y) is located on the Y axis (such as Fig.11 ), the turntable 5 drives the laser rangefinder 7 thereon to rotate 90°, so that the laser rangefinder 7 points to the Y axis. If S is greater than x and y (such as Fig.13 ), then according to the right-angle trigonometric function formula sinα=y / S, the angle α of the horizontal rotation of the laser rangefinder 7 is calculated, and the turntable 5 is controlled to drive the laser rangefinder 7 thereon to rotate to the specified angle;

[0052] S3, the height H of the level 12 is known, and then according to formula a 2 +b 2 =c 2 , calculate the distance L from the laser rangefinder 7 to the coordinate A, and then calculate the angle θ of the laser rangefinder 7 to rotate up and down according to the formula sinθ=S / L, so as to control the turntable 5 and the electric push rod 8 to drive the laser rangefinder 7 to adjust to the specified angle, and the point mapped by the laser rangefinder 7 on the ground is A(x,y);

[0053] S4. Then, according to the size of the steel column base on the drawing, adjust the XY module 3 so that the XY module 3 drives the level 12 to move horizontally on the XY axis, and map points B, C and D on the ground. The position and size of the installation point are determined by points A, B, C and D. The four corners of the steel column base are determined by points A, B, C and D. After the installation point is determined, mark it on the ground. Finally, the XY module 3 drives the folding column 6 to return to its original position, and the turntable 5 and the electric push rod 8 drive the laser rangefinder 7 to restore to its initial state, and locate each installation point of the steel column according to the above operations.

[0054] Fig.10 , Fig.12 and Fig.14 The installation points are respectively on the set X-axis and Y-axis and other positions, and the coordinate diagram of the four points is determined. The XY module 3 drives A to move horizontally three times, and forms points A, B, C, and D on the ground to determine the four corners of the steel column base. The XY module 3 drives the laser rangefinder 7 to move horizontally in the X-axis and Y-axis according to the size of the steel column base, so that points A, B, C, and D represent the positions of the four corners of the steel column base. In this way, the installation point of the steel column is further located to avoid large errors.

[0055] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.

After the installation point is determined, it is marked on the ground. Finally, the XY module (3) drives the folding column (6) to return to its original position, and the turntable (5) and the electric push rod (8) drive the laser rangefinder (7) to restore the initial state. According to the above operations, each installation point of the steel column is located.
